Europe scored a major space success with today’s (Feb. 13) flawless maiden launch of the brand new Vega rocket from Europe’s Spaceport in Kourou, French Guiana.
The four stage Vega lifted off on the VV01 flight at 5:00 a.m. EST (10:00 GMT, 11:00 CET, 07:00 local time) from a new launch pad in South America, conducted a perfectly executed qualification flight and deployed 9 science satellites into Earth orbit.
Vega is a small rocket launcher designed to loft science and Earth observation satellites.

The payload consists of two Italian satellites – ASI’s LARES laser relativity satellite and the University of Bologna’s ALMASat-1 – as well as seven picosatellites provided by European universities: e-St@r (Italy), Goliat (Romania), MaSat-1 (Hungary), PW-Sat (Poland), Robusta (France), UniCubeSat GG (Italy) and Xatcobeo (Spain).

Three of these cubesats were the first ever satellites to be built by Poland, Hungary and Romania. They were constructed by University students who were given a once in a lifetime opportunity by ESA to get practical experience and launch their satellites for free since this was Vega’s first flight.
The 30 meter tall Vega has been been under development for 9 years by the European Space Agency (ESA) and its partners, the Italian Space Agency (ASI), French Space Agency (CNES). Seven Member States contributed to the program including Belgium, France, Italy, the Netherlands, Spain, Sweden and Switzerland as well as industry.
Vega's first launch, dubbed VV01, occurred on Feb 13, 2012 from Europe's Spaceport in Kourou, French Guiana. It carried nine satellites into orbit: LARES, ALMASat-1 and seven Cubesats.

HuartESA can now boast a family of three booster rockets that can service the full range of satellites from small to medium to heavy weight at their rapidly expanding South American Spaceport at the Guiana Space Center.
Vega joins Europe’s stable of launchers including the venerable Ariane V heavy lifter rocket family and the newly inaugurated medium class Russian built Soyuz booster and provides ESA with an enormous commercial leap in the satellite launching arena.
“In a little more than three months, Europe has increased the number of launchers it operates from one to three, widening significantly the range of launch services offered by the European operator Arianespace. There is not anymore one single European satellite which cannot be launched by a European launcher service,” said Jean-Jacques Dordain, Director General of ESA.
“It is a great day for ESA, its Member States, in particularly Italy where Vega was born, for European industry and for Arianespace.”
Dordain noted that an additional 200 workers have been hired in Guiana to meet the needs of Europe’s burgeoning space programs. Whereas budget cutbacks are forcing NASA and its contractors to lay off tens of thousands of people as a result of fallout from the global economic recession.

ESA has already signed commercial contracts for future Vega launches and 5 more Vega rockets are already in production.
Vega’s light launch capacity accommodates a wide range of satellites – from 300 kg to 2500 kg – into a wide variety of orbits, from equatorial to Sun-synchronous.
“Today is a moment of pride for Europe as well as those around 1000 individuals who have been involved in developing the world’s most modern and competitive launcher system for small satellites,” said Antonio Fabrizi, ESA’s Director of Launchers.

28 years ago today, NASA astronaut Bruce McCandless left the relative safety of Challenger’s payload bay and went untethered into orbit around Earth, venturing farther than anyone ever before.
The historic photo above was taken when McCandless was 320 feet from the orbiter — about the length of an American football field, or just shy of the width of the International Space Station.
The free-flying endeavor was possible because of McCandless’ nitrogen-powered jet-propelled backpack, called a Manned Maneuvering Unit (MMU). It attached to the space suit’s life-support system and was operated by hand controls, allowing untethered access to otherwise inaccessible areas of the orbiter and was also used in the deployment, service and retrieval of satellites.

The MMU used a non-contaminating nitrogen propellant that could be recharged in the orbiter. It weighed 140 kg (308 lbs) and has a built-in 35mm camera.
After the Challenger disaster, the MMU was deemed too risky and was discontinued. But for a brief period of time in the early ’80s, humans had the means for really “soaring to new heights”.

The North American continent is literally set ablaze in a confluence of Auroral and Manmade light captured in spectacular new videos snapped by the astronauts serving aboard the International Space Station (ISS).
The Expedition 30 crew has recently filmed lengthy sequences of images that are among the most stunning ever taken by astronauts flying in orbit some 240 miles (385 kilometers) over the United States and Canada.

Teams working at the Crew Earth Observations center at NASA’s Johnson Space Center in Houston, Texas have assembled hundreds of individual still images taken onboard the ISS into a series of amazing videos.
Two videos collected here focus on the East and West coasts of North America and show the path traveled by the station from the crew’s perspective as they photographed the light emitted by hundreds of millions of humans living below and the brilliant light of the Aurora Borealis shining above them.

Now the NASA team has assembled the entire sequence of images taken on January 29, 2012 from 05:33:11 to 05:48:10 GMT into a video -see above.
The orbital pass runs from Central America just southwest of Mexico and continues to the North Atlantic Ocean, northeast of Newfoundland. It begins by looking over Central America towards the Gulf of Mexico and the southeastern United States. As the ISS travels northeast over the gulf, some southeastern United States cities can be distinguished, like New Orleans, Mobile, Jacksonville, and Atlanta. Continuing up the east coast, some northeastern states, like Washington, D.C., Baltimore, Philadelphia, and New York City stand out brightly along the coastline. The Aurora Borealis shines in the background as the pass finishes near Newfoundland
The 2nd video is titled “Across Southwest Canada at Night”
This sequence of shots was taken January 25, 2012 from 12:34:11 to 12:36:28 GMT, on a pass from near the border of British Columbia, Canada and Washington state, near Vancouver Island, to southern Alberta, near Calgary.
The main focus of this video is the Aurora Borealis over Canada, which appears very near the ISS during this short and exciting video.
And don’t forget the fabulous ISS shots of Comet Lovejoy taken in December 2011 by Expedition 30 Commander Dan Burbank.

NASA Budget Cuts in Fiscal Year 2013 will force NASA to kill participation in the joint ESA/NASA collaboration to send two Astrobiology related missions to orbit and land rovers on Mars in 2016 and 2018 - designed to search for evidence of Life. Russia will likely replace the deleted Americans.
[/caption]
America’s hugely successful Mars Exploration program is apparently about to be gutted by Obama Administration officials wielding a hefty budget axe in Washington, D.C. Consequently, Russia has been invited to join the program to replace American science instruments and rockets being scrapped.
NASA’s Fiscal 2013 Budget is due to be announced on Monday, February 13 and its widely reported that the Mars science mission budget will be cut nearly in half as part of a significant decline in funding for NASA’s Planetary Science Division.
The proposed deep slash to the Mars exploration budget would kill NASA’s participation in two new missions dubbed “ExoMars” set to launch in 2016 and 2018 as a joint collaboration with the European Space Agency (ESA).
The ESA/NASA partnership would have dispatched the Trace Gas Orbiter to the Red Planet in 2016 to search for atmospheric methane, a potential signature for microbial life, and an advanced Astrobiology rover to drill deeper into the surface in 2018. These ambitious missions had the best chance yet to determine if Life ever evolved on Mars.
The 2016 and 2018 ExoMars probes were designed to look for evidence of life on Mars and set the stage for follow on missions to retrieve the first ever soil samples from the Red Planet’s surface and eventually land humans on Mars.

The proposed Mars budget cuts will obliterate these top priority science goals for NASA.
The BBC reports that “ a public announcement by NASA of its withdrawal from the ExoMars program will probably come once President Obama’s 2013 Federal Budget Request is submitted.”
A Feb. 9 article in ScienceInsider, a publication of the journal Science, states that “President Barack Obama will propose a $300 million cut in NASA’s planetary science programs as part of his 2013 request for the agency.”
This would amount to a 20% cut from $1.5 Billion in 2012 to $1.2 Billion in 2013. The bulk of that reduction is aimed squarely at purposefully eliminating the ExoMars program. And further deep cuts are planned in coming years !

The Mars budget of about $580 million this year would be radically reduced by over $200 million, thereby necessitating the end of NASA’s participation in ExoMars. These cuts will have a devastating impact on American scientists and engineers working on Mars missions.
The fallout from the looming science funding cuts also caused one longtime and top NASA manager to resign.
According to ScienceInsider, Ed Weiler, NASA’s science mission chief, says he “quit NASA Over Cuts to Mars Program.”
“The Mars program is one of the crown jewels of NASA,” said Ed Weiler to ScienceInsider.
“In what irrational, Homer Simpson world would we single it out for disproportionate cuts?”
“This is not about the science mission directorate, this is not even about NASA. This is about the country. We are the only country in the world that has demonstrated the capability to land anything on Mars. How can we allow that to be undermined?”
Weiler’s resignation from NASA on Sept. 30, 2011 was sudden and quick, virtually from one day to the next. And it came shortly after the successful launch of NASA’s GRAIL lunar probes, when I spoke to Weiler about Mars and NASA’s Planetary Science missions and the gloomy future outlook. Read my earlier Universe Today story about Weiler’s retirement.
Ed Weiler was the Associate Administrator for NASA’s Science Mission Directorate (SMD) and his distinguished career spanned almost 33 years.
The dire wrangling over NASA’s 2013 budget has been ongoing for many months and some of the funding reductions had already leaked out. For example NASA had already notified ESA that the US could not provide funding for the Atlas V launchers in 2016 and 2018. Furthermore, Weiler and other NASA managers told me the 2018 mission was de-scoped from two surface rovers down to just one to try and save the Mars mission program.
ESA is now inviting Russian participation to replace the total American pullout, which will devastate the future of Red Planet science in the US. American scientists and science instruments would be deleted from the 2016 and 2018 ExoMars missions.
The only approved US mission to Mars is the MAVEN orbiter due to blastoff in 2013 – and there are NO cameras aboard MAVEN.
Three Generations of US Mars Rovers - 4th Generation ExoMars rover to be Axed by NASA budget cuts.
NASA is caught in an inescapable squeeze between rising costs for ongoing and ambitious new missions and an extremely tough Federal budget environment with politicians of both political affiliations looking to cut what they can to rein in the deficit, no matter the consequences of “killing the goose that laid the golden egg”.
NASA Watch Editor Keith Cowing wrote; “Details of the FY 2013 NASA budget are starting to trickle out. One of the most prominent changes will be the substantial cut to planetary science at SMD [NASA’s Science Mission Directorate]. At the same time, the agency has to eat $1 billion in Webb telescope overruns – half of which will come out of SMD.”
The cost of the James Webb Space Telescope (JWST) has skyrocketed to $8.7 Billion.
To pay for JWST, NASA is being forced to gut the Mars program and other science missions funded by the same Science Mission Directorate that in the past and present has stirred the public with a mindboggling payoff of astounding science results from many missions that completely reshaped our concept of humankinds place in the Universe.
Meanwhile, China’s space program is rapidly expanding and employing more and more people. China’s scientific and technological prowess and patent applications are increasing and contributing to their fast growing economy as American breakthroughs and capabilities are diminishing.
Under the budget cutting scenario of no vision, the Curiosity Mars Science Laboratory rover will be America’s last Mars rover for a long, long time. Curiosity will thus be the third and last generation of US Mars rovers – 4th generation to be Axed !
Apollo 14's splashdown in the Pacific on Feb. 9, 1971. (NASA/Ed Hengeveld)
On this day in 1971 Apollo 14 astronauts Alan Shepard, Jr., Stuart Roosa and Edgar Mitchell returned to Earth, splashing down in the Pacific Ocean at 21:05 UT (4:05 p.m. EST). They were recovered by the USS New Orleans, and returned to the U.S. by way of American Samoa. But the three men weren’t the only living creatures to come back from the Moon on Feb. 9, 1971… in fact, human astronauts were in the minority that day.
Al, Stu and Ed shared their lunar voyage with nearly 500 trees.
As Shepard and Mitchell gathered samples near their landing site in a region named Fra Mauro, Apollo 14 pilot and ex-smoke jumper Stuart Roosa orbited above in “Kitty Hawk”, the mission’s Command Module. It may sound like a lonely job, but he was far from alone. Within his personal kit were small containers containing 400-500 seeds, part of a joint NASA/USFS project to examine the effects, if any, of space travel on such organisms.
The seeds were selected from a variety of tree species: redwood, loblolly pine, sycamore, Douglas fir, and sweetgum seeds were all chosen to accompany Roosa on his 34 orbits around the Moon.
A control group of the same seed varieties were kept on Earth for comparison.
Stuart Roosa had worked for the Forest Service in the 1950s before becoming an Air Force test pilot and then eventually an Apollo astronaut. Being charged with the care of the seeds was a particularly symbolic assignment for Roosa, who had once fought wildfires as a smoke jumper.
Even though there was a mishap during the decontamination process after return to Earth, wherein some containers burst open and seeds were inadvertently mixed together, many of the seeds successfully germinated at Forest Service stations in Mississippi and California. The seedlings were eventually sent to locations around the country and around the world to commemorate the success of the Apollo program.
There was even a second generation, called half-moon trees.

Many of these “Moon Trees” and their descendants still stand today. In some instances they are marked with a plaque or a sign… in others, no special marking denotes their significance. Those unmarked trees stand as silent reminders of an earlier and perhaps even bolder era of human space flight.
Read more about the Moon Trees on this page by David Williams of NASA’s Goddard Space Flight Center. And if you know of a Moon Tree that is not on Mr. William’s list, please contact him to have it included. Williams has endeavored to locate the whereabouts and status of these trees since 1996, as there had been no systematic records previously kept of them.
“I think when people are aware of the heritage of the trees, they usually take steps to preserve them,” said Williams in recollection of one tree that was nearly knocked down during a building renovation. “But sometimes people aren’t aware. That’s why we want to locate as many as we can soon. We want to have a record that these trees are — or were — a part of these communities, before they’re gone.”

The Lander platform for NASA’s Spirit rover has been photographed in stunning high resolution color for the first time from Mars orbit – just over 8 years after the now legendary robot survived the scorching atmospheric heat of the 6 minute plunge through the Martian atmosphere and bounced to a stop inside Gusev Crater on January 3, 2004.
Spirit’s three petaled landing pad was finally imaged in color by NASA’s powerful Mars Reconnaissance Orbiter (MRO) spacecraft just days ago on January 29, 2012 at 3:04 p.m. local Mars time.
The MRO spacecraft was soaring overhead and captured the image of Spirit’s lander with the high resolution HiRISE camera from a distance of some 262 kilometers, (162 miles).
“HiRISE has never before imaged the actual lander for the Spirit rover in color, [located] on the west side of Bonneville Crater,” writes Alfred McEwen, HiRISE Principal Investigator at the University of Arizona.

While protectively cocooned inside the airbag cushioned lander, Spirit bounced about two dozen times before rolling to rest on the Martian plains about ¼ mile away from Bonneville Crater. Then her landing petals unfurled, the airbags were partially retracted and Spirit eventually drove off the landing pad.
“The lander is still bright, but with a reddish color, probably due to a [Martian] dust cover.”

Spirit initially drove to Bonneville Crater and circumnavigated part way around the rim before speeding off towards the Columbia Hills, about 2 miles to the East. She eventually scaled the summit of Husband Hill and drove down the opposite side to the Home Plate” volcanic feature where she rests today – see travse map below.
“A bright spot from a remnant of the heat shield is still visible on the north rim of Bonneville Crater. The backshell and parachute are still bright, but were not captured in the narrow color swath.”
“The rover itself can still be seen near “Home Plate” in the Columbia Hills, but there is no obvious sign of rover tracks–erased by the wind,” McEwen notes.
Here is a photo taken by Spirit looking back to the lander – now imaged in color from orbit for the first time – for a comparative view, before she drove off forever.
Spirit endured for more than six years of bonus time exploration beyond her planned 90 day mission. And Opportunity is still roving Mars today !

Contrary to popular belief, Tang, Velcro and Teflon (along with the zero-gravity “space” pen) aren’t derived from NASA technology. NASA has, however, developed numerous technologies over the years, which are featured in annual “Spinoff” reports. Yes, “memory” foam mattresses are in fact one such product developed from NASA technologies.
NASA’s latest Spinoff edition features over forty of NASA’s most innovative technologies. The origins of each technology within NASA missions are provided, as well as their “spinoff” to the public as commercial products and/or technologies beneficial to society.
What new technologies have made their way this year from NASA labs and into our homes?
Generally, NASA spinoff technologies have proven useful in health and medicine, transportation, public safety, and consumer goods. Additional benefits from NASA spinoff technology can be found in the environment, information technology, and industrial productivity sectors. Experience has shown that these NASA technologies can help stimulate the economy and create new jobs and businesses in the private sector.
NASA Administrator Charles Bolden states, “This year’s Spinoff demonstrates once again how through productive and innovative partnerships, NASA’s aerospace research brings real returns to the American people in the form of tangible products, services and new jobs. For 35 years, Spinoff has been the definitive resource for those who want to learn how space exploration benefits life on Earth.”
A few highlights from NASA’s “Spinoff 2011” include:
A new firefighting system, influenced by a NASA-derived rocket design that extinguishes fires more quickly than traditional systems, saving lives and property.
Software employing NASA-invented tools to help commercial airlines fly shorter routes and help save millions of gallons of fuel each year, reducing costs to airlines while benefiting the environment.
A fitness monitoring technology developed with the help of NASA expertise that, when fitted in a strap or shirt, can be used to measure and record vital signs. The technology is now in use to monitor the health of professional athletes and members of the armed services.
An emergency response software tool that can capture, analyze and combine data into maps, charts and other information essential to disaster managers responding to events such as wildfires, floods or Earthquakes. This technology can save millions of dollars in losses from disasters and, more importantly, can help save lives when tragedy strikes.
The 2011 spinoff report also includes a special section celebrating commercial technologies derived from NASA’s Space Shuttle Program. Additionally, NASA lists spinoff technologies based on the construction of the International Space Station and work aboard the station. One other section in the report outlines potential benefits of NASA’s future technology investments.
“NASA’s Office of the Chief Technologist has more than a thousand projects underway that will create new knowledge and capabilities, enabling NASA’s future missions,” NASA Chief Technologist Mason Peck adds. “As these investments mature, we can expect new, exciting spinoff technologies transferring from NASA to the marketplace, providing real returns on our investments in innovation.”

Chinese scientists have assembled the highest resolution map ever created of the entire Moon and unveiled a series of global Moon images on Monday, Feb. 6.
The composite Lunar maps were created from over 700 individual images captured by China’s Chang’e-2 spacecraft and released by the country’s State Administration of Science, Technology and Industry for National Defence (SASTIND), according to reports from the state run Xinhua and CCTV new agencies.
“The map and images are the highest-resolution photos of the entirety of the Moon’s surface to be published thus far,” said Liu Dongkui, deputy chief commander of China’s lunar probe project, reports Xinhua.
Of course there are much higher resolution photos of numerous individual locations on the Moon taken from orbit by the spacecraft of other countries and from the surface by NASA’s Apollo lunar landing astronauts as well as unmanned Russian & American lunar landers and rovers.

Chang’e-2 is China’s second lunar probe and achieved orbit around our nearest neighbor in space in October 2010. It was launched on Oct. 1, 2010 and is named after a legendary Chinese moon goddess.
The images were snapped between October 2010 and May 2011 using a charge-coupled device (CCD) stereo camera as the spacecraft flew overhead in a highly elliptical orbit ranging from 15 km to 100 km altitude.
The Chang’e-2 maps have a resolution of 7 meters, which is 17 times greater than from China’s first lunar orbiter; Chang’e-1, launched in 2007.

In fact the maps are detailed enough that Chinese scientists were able to detect traces of the Apollo landers, said Yan Jun, chief application scientist for China’s lunar exploration project.
Chang’e-2 also captured high resolution photos of the “Sinus Iridum”area , or Bay of Rainbows, where China may land their next Moon mission. The camera had the ability to resolve features as small as 1 meter across at the lowest altitude.
The satellite left lunar orbit in June 2011 and is currently orbiting the moon’s second Lagrange Point (L2), located more than 1.5 million km away from Earth.
Chinese space program officials hope for a 2013 liftoff of the Chang’e-3 lunar rover, on what would be China’s first ever landing on another celestial body. China’s next step beyond the rover may be to attempt a lunar sample return mission in 2017.
Demonstrating the ability to successfully conduct an unmanned lunar landing is a key milestone that must be achieved before China can land astronauts on the Moon, perhaps within the next decade.
NASA’s twin GRAIL spacecraft recently achieved Lunar orbit over the New Year’s weekend. The duo of probes were just renamed as “Ebb and Flow” – the winning entries in an essay naming contest submitted by 4th Grade US students from Bozeman, Montana.
At this time NASA does not have the funding or an approved robotic lunar landing mission, due to severe budget cuts.And even worse NASA cuts will be announced shortly !
Russia hopes to send the Lunar Glob spacecraft to land on the Moon around 2015.
Since the United States has unilaterally scuttled its plans to return American astronauts to the Moon’s surface, it’s very possible that the next flag planted on the Moon by humans will be Chinese.
We’ve featured wonderful time-lapse videos taken from the Space Station many times and each one is amazing to watch, but here’s something a little different: by taking photos at the rate of one per second and assembling them into a time-lapse, we can get a sense of what it’s like to orbit the planet at 240 miles up, 17,500 mph… in real time. Absolutely amazing!

Haul out your red-cyan 3-D anaglyph glasses and lets go whirling around Vesta and sledding down mountains to greet the alien Snowman! The sights are fabulous !
The Dawn imaging group based at the German Aerospace Center (DLR), in Berlin, Germany and led by team member Ralf Jaumann has released a trio of new high resolution 3-D images that are the most vivid anaglyphs yet published by the international science team.
The lead anaglyph shows the highly varied topography of the Eastern Hemisphere of Vesta and was taken during the final approach phase as Dawn was about 5,200 kilometers (3,200 miles) away and preparing to achieve orbit in July 2011.
The heavily cratered northern region is at top and is only partially illuminated because of Vesta’s tilted angle to the Sun at that time of year. Younger craters are overlain onto many older and more degraded craters. The equatorial region is dominated by the mysterious troughs which encircle most of Vesta and may have formed as a result of a gargantuan gong, eons ago.
The southern hemisphere exhibits fewer craters than in the northern hemisphere. Look closely at the bottom left and you’ll see the huge central mountain complex of the Rheasilvia impact basin visibly protruding out from Vesta’s south polar region.
This next 3-D image shows a close-up of the South Pole Mountain at the center of the Rheasilvia Impact basin otherwise known as the “Mount Everest of Vesta”.

This anaglyph shows the central complex and huge mountain in Vesta’s Rheasilvia impact basin at the South Pole. Does water ice lurk beneath the South Pole ?
Credit: NASA/JPL-Caltech/UCLA/MPS/DLR/IDA.
The central complex is approximately 200 kilometers (120 miles) in diameter and is approximately 20 kilometers (12 miles) tall and is therefore about two and a half times taller than Earth’s Mount Everest!
Be sure to take a long look inside the deep craters and hummocky terrain surrounding “Mount Everest”.
A recent study concludes that, in theory, Vesta’s interior is cold enough for water ice to lurk beneath the North and South poles.
Finally lets gaze at the trio of craters that make up the “Snowman” in the 3-D image snapped in August 2011 as Dawn was orbiting at about 2,700 kilometers (1,700 miles) altitude. The three craters are named Minucia, Marcia and Calpurnia from top to bottom. Their diameters respectively are; 24 kilometers (15 miles), 53 kilometers (33 miles) and 63 kilometers (40 miles).

The three craters are named Minucia, Marcia and Calpurnia from top to bottom. They are 24 kilometers (15 miles), 53 kilometers (33 miles) and 63 kilometers (40 miles) in diameter, respectively. Image resolution is about 250 meters (820 feet) per pixel. Credit: NASA/JPL-Caltech/UCLA/MPS/DLR/IDA.
It is likely that Marcia and Calpurnia formed from the impact of a binary asteroid and that Minucia formed in a later impact. The smooth region around the craters is the ejecta blanket.

Vesta is the second most massive asteroid in the main Asteroid Belt between Mars and Jupiter. It is 330 miles (530 km) in diameter.
Dawn is the first spacecraft from Earth to visit Vesta. It achieved orbit in July 2011 for a year long mission. Dawn will fire up its ion propulsion thrusters in July 2012 to spiral out of orbit and sail to Ceres, the biggest asteroid of them all !
Vesta and Ceres are also considered to be protoplanets.
